Description of the complex

The complex has two types of control:

- centralized management (TSU);

- autonomous control (AU).

Regardless of the control mode, the complex operates in the following order.

The determination of the coordinates of objects by the radiation of radio-electronic means (RES) placed on the objects, and their subsequent trajectory tracking (passive radar) is provided by receiving and processing the radio emission of the RES from different spatial points and then solving the problem of determining the coordinates of the sources of radio emission (IRI) by the differential-ranging method .

During the operation of the complex, the receiver of a panoramic survey of SOI detects the signals of the onboard RES in the space zone circular in azimuth and 30 ° in elevation in the instantaneous frequency band of 16 GHz in the range from 2 to 18 GHz and measures their parameters (carrier frequency, spectrum width )

Based on the information received, target designation teams are formed (carrier frequency, sector and spectrum width), which are transmitted to the leading SOP of the complex.

On the leading SOP, a team is developed according to which the RDM receivers of all SOPs for a period of not more than 1 ms are set in a given sector and at a given frequency.

In accordance with the adopted command, each SOP carries out the detection of onboard RES signals, measures their parameters (detection time, frequency, pulse duration, spectrum width, type of modulation), transfers codograms of the processed signals from the slave SOPs to the leading SOP. At the leading SOP, the following is carried out: combining the signal information of all SOPs with inter-post pulse-by-axis coordinate identification by belonging to the same IRI, determining the pulse repetition period and calculating the coordinates of the IRI, trajectory filtering of marks.

Information about the parameters of the IRI during the reception of pulses is subjected to statistical processing in real time, which allows you to obtain the specified accuracy characteristics.

At the leading SOP, the coordinates of the radiation sources are determined from the measured signal parameters.

The received information is transmitted to the SDI to identify targets by the recognition parameters of classes or types of radio electronic equipment and the linking of traces.

The ability to determine the coordinates of the IRI allows you to implement a tracking mode of radiation sources not only with the formation of trace information, but also the motion vector of the object. The presence of the object’s path of movement creates the possibility of forming an extrapolated value of the position of the object, which can be used if information from three SOPs was not received at the next review cycle.

Upon receipt of target designation, a detection and direction finding (SOP) station provides switching of receiving devices to the antenna system in a given sector and tuning to the required frequency.

The functioning of SOPs as part of the complex, the exchange of information and control commands in real time, is ensured by the synchronization of time scales of spatially separated SOPs.

The introduction of a single-pulse direction finding mode additionally in SOPs significantly improves the standard deviation of direction finding from 45 ° to 5 °, which makes it possible to use SOPs as a RTR station.

Three sets of communication lines provide communication between the master and slave SOPs at ranges up to 30 km. Control lines and data packets are transmitted over communication lines.

The information processing station provides the following basic functions:

- panoramic view with an instantaneous bandwidth of 16 GHz in the range of 2-18 GHz;

- management of SOP complex;

- exchange of information with a higher command post and other external sources and consumers of information;

- detection of signals from airborne radioelectronic systems in the spatial zone around the azimuth and 30 ° in elevation and measuring their parameters (carrier frequency, spectrum width);

- target designation (frequency and sector) of the leading SOP complex;

- identification of targets by the signal parameters of the IRI received from the leading SOP complex;

- trajectory tracking of targets according to the coordinate information about the IRI received from the leading SOP complex;

- documentation of information.

Antenna receiving module for panoramic viewing (APM-PO) functionally includes:

- antenna system;

- digital broadband radio receiver panoramic view (TsSh-RPU);

- sources of secondary power supply (VEP).

The APM-PO antenna system includes:

- 16 horn and 16 log-periodic antennas;

- low noise antenna amplifiers (LNA);

- electronic switching device;

- communication interfaces.

Each antenna (horn or log-periodic) has a radiation pattern of 45 ° in the azimuthal and 30 ° in elevation planes with the intersection of the partial antenna patterns (BOTTOM) at 3 dB.

At the output of each log-periodic antenna, broadband low-noise amplifiers (LNAs) with a noise figure of not more than 4 dB are installed.

The outputs of each LNA through the adders and control cells are connected to a broadband radio receiver consisting of 32 receiving channels with a bandwidth of 500 MHz and providing simultaneous reception of signals in the operating frequency band of 2-18 GHz for a set time (5 or 10 ms) from the azimuthal sector 45 °. Detection of IRI and measurement of signal characteristics is carried out by the signal processing device. At the next point in time, all receiving devices are connected to the antennas (LNA) of the next azimuth sector. Thus, in 40 ms (5 ms × 8) or 80 ms (10 ms × 8), a circular overview of the space is carried out.

After supplying power to the antenna-receiving panoramic viewing module, a built-in monitoring of the device’s operability is performed and, if the result is positive, a spatial survey of the reconnaissance zone, detection of signals from the onboard radio electronic equipment, measurement of their parameters (carrier frequency and spectral width) are carried out.

Spatial-frequency review of the receiving device panoramic overview is as follows.

At the commands from the central processing unit (CPU) of the SDI, the output of one of six log-periodic antennas serving the 60 ° sector in azimuth is connected to the digital broadband receiving device via a 6 × 1 PRK.

TsSH-RPU provides a panoramic view with an instant band of 16 GHz of the entire frequency range of 2-18 GHz of this spatial sector.

The results of viewing this spatial sector in the form of the measured characteristics of the detected IRI (frequency and width of the spectrum) or the absence of IRI in this spatial sector are transmitted to the central processor of the SDI. According to the results of viewing the CPU, the TsSh-RPU switches to the output of the next log-periodic antenna serving another 60 ° spatial sector. Thus, a sequential round-robin review of the space is carried out and target designation based on the detected IRI in the RDM system is performed.

In the process of operation of a passive radar, the SOI performs:

- formation and transfer to SOP management teams and receiving reports on their implementation;

- receiving information from the leading SOP about the status of stations, signal characteristics of the IRI and their coordinates;

- recognition of targets according to the signal characteristics of the IRI and their trajectory tracking;

- transfer to the CPSU information on the coordinates and parameters of the movement of targets, types and (or) classes of onboard RES;

- reception from the CPSU of the complex management commands and transmission of reports on their implementation;

- transmission of information on the coordinates and parameters of target movement, type and (or) class of their airborne radars to the customer’s radar and control system;

- display of information about the air and radio environment on AWP1 and AWP2;

- documentation of information circulating in the data transmission channels and the results of the SDI.

The interface between the SDI and the leading SOP is carried out on a fiber-optic communication line. In case of failure of the leading SOP or fiber optic link with it, the functioning of the complex is ensured by designating any of the remaining SOPs as leading and controlling it via a radio channel through a router.

The SOI and VKP are interfaced via a radio channel through a router (main communication line), fiber optic link or a wired communication line.

The SDI is interfaced with the radar, as well as with the customer’s CP of the Customer’s air defense system via FOCL or a wired communication line.

The SDI information processing algorithm provides the following software list:

- a set of exchange programs;

- a set of functional programs;

- a set of operator interface programs;

- a set of service programs;

- a set of programs for working with maps (GIS).

The complex of exchange programs includes:

- exchange program with SOP;

- exchange program with the CPSU and data transmission to the radar and control system of the Customer’s air defense system.

The exchange program with SOP provides the transmission of target designation and control SOP commands, the reception of coordinate and signal information about IRI.

SDI operates in the following modes of operation: “Data Entry”; "Work"; "The control"; "Training"; "Playback"; "Documentation."

In the "Data Entry" mode, the initial following main data groups are recorded in the AWP memory:

- used in automated processing of information about goals in the "Work" mode;

- radio data (RD) containing settings for the router, radio stations and radio channel.

When exchanging SDI data with SOPs and CPSUs via fiber-optic communication lines (FOCL), exchange parameters for FOCL are introduced.

In case of interfacing SDI via wire lines of communication with the VKP, radar and air defense CP through the ADF, the initial data are entered into each ADF set with the AWS, which determine the operation modes and parameters of the ADF in each direction.

In the “Work” mode, the main functions of the SDI are implemented for controlling the station equipment, SOP and the complex as a whole, identifying targets and their support, pairing with the CPSU and other subscribers using communication and ADF, as well as information processing systems.

In the “Control” mode, the basic functions are implemented for monitoring the health of the equipment and determining the faulty element of the station to a typical replacement element.
